What happens to the melanin in the hair that has been alleviated? chemistry project. : / Also, are there special ingredients that cause hair color ash blonde? Thank you in advance. : D
A lock of hair has 3 layers, pith, cortex and cuticle. The medulla is the innermost layer, a bit like the thread that runs inside the rubber coating of a coaxial cable. The cuticle is the spongy inner layer that surrounds the spinal cord, much like the pithy part in a flower stalk, and finally the outer layer, the cuticle is like overlapping scales similar to fish scales or the bark of trees.
When hair is chemically reduced, the external balance lift and loosen, allowing the solution to penetrate into the cortex, where the molecules are colored. The bubbling action and surrounds alkaline oxide and the color molecules (peroxide used in hair dyes is H2O2, so the action of oxidation) and the scales of the cuticle closed to allow molecules of oxidized color (melanin) to drag and they are then removed by rinsing. This leaves the hair porous and rough, or damaged, because part of the structure of hair is now missing and has been chemically modified.
Add color lightened hair is a process of replacing these "missing color molecules" with the new (artificial) them.
To obtain an ash blonde color, it involves using shades cooler in the base color, if you know the color wheel, you know that purple is the gold face of the wheel, and green is opposite red. Using a base color of purple, you can help offset or cancel the warm gold (copper) tones in blonde hair, and using basic color green can help neutralize the red tones ..
melanin, which is a protein changes conformation when reduced.
